PORTABLE STOVE.

SPECIFICATION forming part of Letters Patent No. 241,194, dated May 10, 1881.

Application filed November 1, 1879.

To all whom it may concern:

Be it known that I, NICHOLAS ORoTsEN- BURG, of J anesville, in the county of Rock and State of Wisconsin, have invented a certain new and useful Improvement in Oil-Stoves, of

which the following is a specification.

The object I have in view is to produce a sim ple and cheap oil-stove, which will be economical in its use of oil and will produce complete combustion of the gases thrown off by the flames; which will be clean and convenient in use,will be constructed so that, without detracting from its usefulness for cooking purposes, it can be employed to heat fiat-irons, no separate I 5 attachment for that purpose being necessary, will not require chimneys for the separate flames to promote draft and produce combustion, and will possess advantages in several other particulars, hereinafter mentioned, over the oil-stoves heretofore made; and my invention therein consists in the several novel features of construction and in the various novel combinations of the operative parts, all as more fully hereinafter explained, and pointed out by 5 the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is a perspective view of the oil-stove; Fig. 2, a top view of the same with the heating-drum thrown back; Fig. 3, a

3 central vertical section of the oil-stove when the heating-drum is in an upri ght position; Fig. 4, a top View with the heating-drum removed, the horizontal diaphragm being shown in position over the cones; and Fig. 5, a separate top view of the annular base.

Like letters denote corresponding parts in all the figures.

A is the base of the stove, made annular in form, and having feet a, upon which it rests,

; 4 such feet raising the base sufficiently to allow a free circulation of air under the same. At its top the annular base has an inwardly-projectin g flange, a, in which a number of slots, 1), are formed.

B is the oil-reservoir, of circular form, which is removably held in the annular base by a number of pins, 1), projecting outwardly from its upper edge, and resting on the inwardly-projecting flange a. of the base. In removing the reservoir from or attaching it to the base the pins 1) pass through the slots 1). The reservoir being hung to the flange a, a clear open space, B, is formed around the reservoir and between the same and the annular base, in which space air circulates and assists to keep the oil-reservoir cool. The slots 1) form air-exit openings at the top of this space, so that a change of air in such space will continually take place. The reservoir B has a flange, 0, turned up around its bottom edge, to catch any oil that may run down the sides of such reservoir, and it has a fillin g-openin g on its top, closed bya screw-cap, d.

From the reservoir rise the flat wick-tubes 0, preferably three in number, which have the usual wick-adjusting stems and wheels. Below the wick-adj ustin g devices each tube is pro vided with lateral slots f, located opposite each other and extending nearly the entire width of the tubes, sufiicient metal only being left at the edges of the wick-tubes to give them the necessary strength. These slots cut off the heat, which would otherwise be conducted down the sides of the wick-tubes to the oil-reservoir. They allow any gases that may collect in the oil-reservoir to escape, and admit fresh air into the wick-tubes, so that the same will commingle with the oil and promote combustion. These slotted wick-tubes Iintend to make the subject-matter of another application for patent, and therefore I do not claim them, broadly, in this application.

From the periphery of the annular bas'e rise three or more posts, 9, upon which the coneplate 0 rests, such cone-plate being hinged to one of such posts, as shown, so that the coneplate and the heating-drum supported thereby can be thrown back to expose the parts below.

Below the c0ne-plate a short distance, and between the same and the oil-reservoir, is situated a circular reflector, D, of bright sheet metal. This reflector is disk-shaped or concave on its upper side, and is imperforate. It is intended to reflect or throw the heat upwardly, so as to confine the heat as much as possible to the heating-drum, and for that pur- 5 pose is made im perforate and of bright metal.

The reflector D has slots, through which the wick-tubes project, and it is supported in any suitable manner.

Below the reflector is a plate or ring, it, which is soldered to the wick-tubes.

To the edge of the reflector D is secured a perforated metallic band, J, extending upwardly to the cone-plate, but not connected therewith. Through this perforated band air passes to feed the flames.

Below the plate It the center of the oil-reservoir is protected by a plate, i,raised above the reservoir by feet; or this plate 5 may cover the whole upper surface of the oil-reservoir.

The cone-plate C has cast therewith the cones 70, provided with slots coincidingin size and position with the wick-tubes that form the burners.

Gr is the heating-drum, made of sheet metal in cylindrical form, and having a number of mica-covered windows, 9, in its flame-chamber G, so that the condition of the flames can be readily observed, and the stove will be useful for illuminating purposes. The sheet-metal heatin g-drum sets within the upwardly-proj ecting edge h of the cone-plate, to which it is secured by suitable means. This upwardly-projecting edge h has slots at intervals, which register with slots in the lower edge of the drum G, forming a number of air-openings, 0, which admit air to the interior of the drum just above the cone-plate.

A short distance above the air-openings 0 the drum has a horizontal diaphragm, H, provided with holes through which the cones project. This diaphragm is notched at a number of points around its edge, producing air-openingsp, Fig. 4, connecting the shallow air-chamber below this diaphragm with the flame-chamber G above it. The diaphragm H protects the cone-plate from being heated by direct radiation from the flame-chamber, while the fresh air which enters through the openings 0 keeps such cone-plate from becoming highly heated,

and such air, being itself heated by circulation among the cones and over the cone-plate, is discharged upwardly, through the openings 1), into the flame-chamber G ,where it produces the combustion of the unconsumed gases thrown off by the flames.

At the upper end of the flame-chamber G and a short distance from the upper edge of the drum G is situated a head, E, which is secured at the front and rear to the walls of the drum, and at the sides is turned up so as to leave long openings 1, through which the products of combustion from the flame-chamber pass upwardly. The center of the head E is provided with a single large opening of suitable shape, which is closed by a removable lid, 1, Fig. 3.

The space below the head E, and between the same and the diaphragm H, forms the flame-chamber G, before referred to, which is a single chamber without chimneys or vertical partitions, in which the products of combustion from all the burners commingle and are consumed, and through which they pass in a single volume.

The drum, above the head E and on a level with the upper side of such head, has an opening, F, on one side extending to the top of the drum, and large enough to admit the body of a flat-iron. This opening F is closed by a door (not shown) when the stove is used for baking, as will be presently explained.

Upon the top edge of the sheet-metal drum is secured a cast-metal ring, I, which has a shoulder adapted to receive all stove-furniture of the size for which itis made. This ring extends over the opening F; but the ring is not complete above such opening, being there severed by a slot, at, wide enough to allow the shanks of a fiatiron handle to pass through it.

A removable cover, 0, provided with slot m, extending from the edge diametrically past its center, for receiving the shanks of a flat-iron handle, is placed upon the ring I when flatirons are to be heated. The lid 1 is also placed in position so that the faces of the flat-irons will not be smoked, while the heat from the flame-chamber passes through the long side openings, l, into the flat-iron chamber, and surrounds the flat-iron placed on the head E, and then passes off at the opening F. The handle of the flat-iron being situated above the slotted cover 0, remains comparatively cool.

For cooking or frying eatables or heating water, the lid 1' is removed and the pot or fryin g-pan is placed upon the ring I, fitting closely the shoulder on the same. The products of combustion rise through the center of the head E and through the openings l, and, after circulating around the bottom of the pot or fryingpan, pass off horizontally through the opening F. By directing the products of combustion in this rnanner,instead of allowing them to pass off freely at all points around the edge of the pot or frying-pan, they are concentrated and forced more intimately into contact with the cooking-vessel, and consequently give off more of their heat.

When a baking-oven, such as is ordinarily 'used with oil-stoves, is placed upon the ring I,

the opening F is closed by its door, (not shown,) so that the products of combustion will all pass up around the oven.

The heating-drum, it will be seen, is constructed to serve as a flat-iron heater in addition to its uses for cookin g purposes. This peculiarity of construction does away with one of the attachments heretofore necessary to be purchased with each oil-stove, and,in addition, adapts the stove particularly for use in tailorshops, laundries, and elsewhere where the heatin g of flat-irons would be the primary object.

What I claim as my invention is- 1.
